Where does the Safety Measurement System (SMS) get its data from?
Answer
SMS gets a monthly snapshot of data from the Federal Motor Carrier Safety Administration
(FMCSA) national database, the Motor Carrier Management Information System (MCMIS).
SMS pulls the previous 24 months of roadside inspection data from MCMIS and State-reported
commercial motor vehicle crashes and motor carrier registration/Census data and
results from Federal and State investigations conducted within the previous 12 months.
